A. M. LANE METALLIC WINDOW SASH July 21, 1931.

Filed Oct. l2, 1929 `Parana-1d July 21, 1931 maman STATES .ALFRED M. IiANE, OF ST. LOUIS, MISSOURI METALLIC SASE Application led October-12, ,1929. Serial No. 399,141.

This invention relates to metallic frames,

' particularly to metallic frames for Window sashes. Heretofore, window sashes have been made with metal frames; but they have been 5 subject to divers disadvantages. 'The 4more common disadvantages are'tliat theframes are more or less iiimsy in constructionrand thus permit winding or twisting ofthe or else they are made with r'ails ofsyheavy l0 cross-section and are thus diiiicult .to operate and unncessarily expensive; many of themI are-of more or lessunsightly appearance due' to the ein loyment of commercial 4roll sections for t e frames; 'and' usually it is' quite i5 diicult or impracticable to protect the parts against damage from rust. The obj ect o f the present invention is to overcome Athese d1sad-' vantages and to produce a lightwelght metallic window sash ofy neat appearance, adapted (25 for economic manufacture, of great strengthv and rigidity and well adapted for repair "and replacement 'of parts, and for use with wmdows of various types and designs.- It consists in the partsA and in the' combinations En and arran ements of parts hereinafter described an claimed. I

- In theA accompanyin drawings, which form part of this spec' cation and wherein like numerals refer to like parts wherever Flig. 1 is an elevation of a metallic wmdow sash embodying my invention, h

Fig. 2 is an enlarged cross-section on the line 2-2inFig'. 1,

Fig. 3 is a similar cross-sectionshowing an arrangement for`sec'uring a hinge or other fitting to the sash; and

Fig. 4 4is a similar s'ectionshowing a modified'ar'rangement for securing the s lit ornamental-casin to the' main frame o the sash.

l My metallic window sash comprises a continuous one-piece tubular main fram'e A made o al -lengthof seamless steel tubing 1 which` is bent tothe desired shape and has its ends disposedin abuttin relation and welded together, as `at 2, to orm said frame.

If desired', the tubular main frame A of saidv lsash may be' ,separate lengths of tubing with their ad'acent ends mitered and vum welded-togethera; e'cgrners of the frame.

As shown in the drawings, the tubing is of a cross-sectional shape, preferably circular, welladapted to resist forces which tend to cause winding or twisting of the frame.

l The`tubular main frame A is covered by or encased within a metallic ornamental and .I'otective outside frame or casing B, which also serves as a seat for the sash pane 3. For purposes of assembly and removal, the outside frame B is split vertically along a line 4 passing through the longitudinal center line of'the tubing 1 of the main fra-me A; that issaid outside frame B com rises outside and inside frame sections' an 6, respectively, that are grooved to fit the tubing and to bring them into substantially abutting relation along their innerfand outer edges. As shown in Fig..2 of the drawings, the innerv and louter frame sections 5 and 6, respectively, ofthe outside frame B may be permanent- 7 ly secured together along their adjacent in- 'side and outside edges as by lines of welding 7 or, as shown in Fig. 4 of the drawings, said outside frame sections may be removably sehured together by means of clips 8 that are disposed. cross-wise of the j oints-between said frame sections and havey bent end portions 9 that t within recessesv or longitudinal channels 10 rovided therefor in the inner and outer edges of said sections. The inner margin of the inner frame'section 5 of the ornamental outside framepor casin B is'provided with a longitudinal outstan ing flange or projection 11 which serves as a seat for the sash pane 3, which, in accordance with 'common practice,is held in position by means of putty 13. The sash pane 3 is held in position before the application ofthe putty 13 by, means of metallic glazing springs 14.- comprising a folded portion 15 adapted to bear against the outside face of said sash pane and laterally projecting anges 16, whose ends are bent to fit within the longitudinal clamping receiving grooves 10 in the inner edges of the inner and outer frame lsections 5 and 6 ofthe outside frame` B.

The portions of the ornamental casing o'r frame B which"form the edges o f'the sash frame may be provided with edge iiangesl'? adapted to overlap or slidably engage the window frame according to the type of window in which the sash is to be mounted. As illustrated in Fig. 3, hinges, handles, pivots or other fittings 18 may be secured to the sash by means of a screw 19 which extends through holes provided therefor in diametrically opposite sides of the tubing l of the main frame A, one of the openings being counterpunched, as at 20, to accommodate the countersunk head 21 of said screw. The end of the screw 19 extends through an opening provided therefor in one of the frame sections of the ornamental outside casing or frame B and is threaded into a nut 22 seated in a conical opening provided therefor in the fitting 18. With this arrangement, the fitting 18 may be clamped tightly against the vertical face of the frame B by tightening the screw 19. l p

The hereinbefore described construction has numerous advantages. It provides a neat, lightweight metallic window sash whose tubular inside or main frame A is well adapted to resist any strains tending to distort the frame of the sash. The frame A is protected by and concealed within an outside frame or casing B which supports the sash pane and may be of any desired ornamental design or any shape to adapt the sash for use with different types and designs of windows. The outside frame B may be readily removed to permit the tubular inside frame A to be painted; andsaid outside frame may be made of different materials such, for instance, as steel, zinc, bronze, brass, aluminum or wood. For example, the outside frame section 6 of the split outside frame or casing B may be made of rust resisting metals, while the inner section 5 of said casing may be made of steel or wood to match the finish on the inside of the building.

Obviously, the hereinbefore described construction admits of considerable modification Without departing from the invention, therefore, I do not'wish to be limited to the precise shapes and arrangements shown and described.

What I claim is:

1. A metallic frame comprising a continuous one-piece metallic supporting frame, and a casing completely enclosing said metallic supporting frame.

2. A metallic window sash comprising a y one-piece tubular supporting frame, andv a casing completely enclosing said tubularsupporting frame.

3.1A metallic Window sash comprising a one-piece tubular main frame, and a frame completely enclosing said tubular main frame.
